HAIRPIN.

Specification of Letters Patent.

Patented June a, 1922.

Application filed. May 1'7, 1920. Serial No. 381.959.

T 0 all whom it may concern:

Be it known that I, lViLLiAir A. P. CATH- CART, a citizen of the UnitedStates, residing at Honolulu, in the county of Honolulu and Territory ofHawaii, have invented new and useful Improvements in Hairpins, of whichthe following is a spec fication.

This invention relates toliair pins and has for its object an improvedform of hair pin in which is provided an auxiliary and relatively smallpin locatedat the bight por tion of the main pin, the ends of thisauxiliary pin being formed close together whereby the auxiliary pin willconstitute a lock for holding hair firmly and against accidentaldisplacement.

An important object is the provision of a pin of this character in whichthe main pin is crinkled or formed serpentine, this crinkling beingdisposed at right angles compared with the crinkling of the ordinaryhair pin.

Another object is the provision of a hair pin of this character in whichthe sides of the auxiliary pin are also formed serpentine whereby toassist in holding hair firmly.

With the above and other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings inwhich- Figure 1 is a front elevation of a pin con structed in accordancewith my invention, and

Figure 2 is a side elevation.

Referring more particularly to the drawings, the numeral 10 designatesthe main pin which is of U-shape and which is formed of two lengths ofwire 11; these lengths being twisted together, as shown at 12, at thebight portion of themain pin and having their'shorter ends 13 disposedbetween the sides of the main pin. The sides of the main pin arecrinkled or formed serpentine, as shown at A, and the serpentineportions lie in parallel planes instead of in the same plane, as is theordinary construction.

In order that the auxiliary pin 15 formed by the shorter ends of thelengths of wire may be rendered more secure in its locking action uponthe hair, the terminals of the end portions 13 are directed toward eachother, as shown at 17, and then extend parallel, as shown at 18, wherebyto form a constricted entrance opening 19 leading into the space 20within the inner or auxiliary pin.

The hair pin is used in the ordinary manner and when pushed into place abunch of hair will be engaged between and be forced through theconstricted entrance opening 19 to the auxiliary pin and be subsequentlydisposed within the space 20. As the spade 20 is considerably largerthan the opening 19 the bunch of hair will naturally expand and theresult is that it is not likely to pull out of the auxiliary pinaccidentally.

From the foregoing description and a study of the drawings it will beapparent that I have thus provided a very simply constructed andconsequently inexpensive hair pin which will. be extremely secure in itsholding action upon the hair and which will consequently be highlyeflicient.

While I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, con-- struction, and arrangement of partsas will not depart from the spirit of the invention or the scope of thesubjoined claim.

Having thus described my invention, I claim:

A hair pin formed from a pair of similar wire members of U-shape, eachhaving one long and one short leg, said wire members being arranged inthe same plane, the junctures of the shorter legs with the bightportions'of the wire members being twisted together whereby the longerlegs will define a hair pin proper and the shorter legs will be disposedbetween the longer legs whereby to constitute an auxiliary pin, thelonger legs being parallel and formed serpentine throughout a portion oftheir length and the shorter legs constituting the auxiliary pin havingtheir end portions disposed coinparatively close together and paralleland WILLIAM A.
